【问题描述】：
特别是在 opennmt-py 中。现在有很多关于这个话题的问题，例如Getting alignment/attention during translation in OpenNMT-py和opennmt论坛上的以下线程https://github.com/OpenNMT/OpenNMT-py/issues/575。我使用后者建议的代码。然而，似乎没有人能解决我遇到的问题。我尝试运行以下简单的 sn-p 代码。
import onmt
import onmt.inputters
import onmt.translate
import onmt.model_builder
from collections import namedtuple
Opt = namedtuple('Opt', ['models', 'data_type', 'reuse_copy_attn', "gpu"])
opt = Opt("/home/Desktop/hidden-att/model/hidden-2/seed-0/LSTMlang1_step_400.pt", "text",False, 0)
fields, model, model_opt = onmt.model_builder.load_test_model(opt,{"reuse_copy_attn":False})
我得到了这个错误跟踪。
Traceback (most recent call last):

raise type(e)(msg)
AttributeError: 'dict' object has no attribute 'seek'. You can only torch.load from a file that is seekable. Please pre-load the data into a buffer like io.BytesIO and try to load from it instead.
那么有没有人经历过并解决了这个问题？或者知道去哪里看？我猜这与加载的文件有关，但它是用 opennmt-py 以相当标准的方式训练的。
